Each was 10 inches because she had 95 and 95-15=40 divided by 4 = 10
Let x= Kiera, y=Larry, z=Gita
"Kiera picked twice as many pounds as Larry" x=2y
"Kiera picked 3 times as many pounds as Gita" x=3z
"Total weight is 8360" x+y+z=8360
substitute in values
x+y+z=8360
3z+1.5z+z=8360
z=1520
x= 3*1520=4560
y=4560/2=2280
F(-2) = 2• 3^-2
f(-2)= 2• 1/ (3^2)
f(-2) = 2/9
Answer is d.
A. Yes, it's true that the domain is {x | x is a real number}.
B. No, the range of f is (-∞, 0].
C. No, f is only decreasing over the interval (0, ∞).
D. Yes, The point (0,0) is a maximum.
E. No, since (0,0) is already a maximum and it's a zero so there is only one x-intercept.
